There is nothing wrong with high RPM inrunners, its all about quality. Even the Taiwan made 210-8XL motor spins at 58K+ rpm in the XF fan with utter reliability.

This GWS fan is running around 35-37,000rpm, hardly high rpm

What we have here is a poor QC situation from another overpriced Chinese motor. Its funny, the first batch of 2040 size motors I got were perfect, then things moved to China and I had 5 motors with shafts bent or ground off centre, 3 with end caps coming loose, 2 with shorted exit wires. No magnet issues though.

Could one of the guys who has flown the J-10 please post a photo of the battery area? I've looked through the manual but can't figure out how the pack is going to sit seeing as the canard servo seems to be in the batt tray. Does your pack interfere with the servo arm and linkage?

Here is a photo of my battery installed. I have not installed the canard and its servo yet but their positions are shown on the photo. The canard joining rod is 66 mm in front of my battery. and the canard servo is 115 mm ahead of the battery.

Yes I have flown it about 15 to 17 times already
No nose heavy at all glides in nicely with a nose high attitude as matter of fact
I have no idea the batteries weight
3300 Mah
I did open the stock battery compartment to fit this battery but turned out I couldn't even put it there
